How to join two point files using FME-geographic?
The two files occupy the same area. For each of the x,y points in the shp file, I would like to find the nearest x,y point in the point cloud file and pass the corresponding point cloud z value to the attribute table of the shp file. I would also like to avoid converting the point cloud to any other format (due to file sizes)
What is the purpose of the spatialrelator in FME?
SpatialRelator. Determines what type of spatial (topological) relationships exist between sets of point, line, area, and text features. Tags – but does not alter the geometry of – features when selected relationships exist, and performs a spatial join to optionally copy attributes between…
What does spatial joins mean in FME Workbench?
Spatial Joins. Spatial Join Transformers. These are transformers that join data on the basis of a spatial relationship. There are many of these in FME Workbench, but the following are some of the key ones.
Which is an example of a spatial join?
For example the PointOnAreaOverlayer carries out a spatial join on points that fall inside area (polygon) features. As the help explains, “Each point receives the attributes of the area (s) it is contained in, and each containing area receives the attributes of each point it contains.”
How does the spatialrelator work in FME desktop?

What are the Transformers for spatial joins in FME?
These are transformers that join data on the basis of a spatial relationship. There are many of these in FME Workbench, but the following are some of the key ones. Overlayers. There are a number of different “overlayer” transformers, each handling a different form of overlay.
How to make spatial join between point files?
Use a CoordinateExtractor to fetch the Z value for each and a 2DForcer to flatten the data. Then you could use the NeighborFinder to get what you need. Amendment: Having thought about it, there is a quicker method.
